HTML code is altered by wordpress

Hi there,

I’m trying to some HTML code into a blog post. I enter it into the html editor but once the site is displayed, and I select “view code” it comes up quite differently. Is there any way to force wordpress to stop changing it?

You can see the site at http://www.goodbadandbogus.com.

The code I want is: <span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&rft.jtitle=The+New+England+journal+of+medicine&rft_id=info%3Apmid%2F20130250&rfr_id=info%3Asid%2Fresearchblogging.org&rft.atitle=Willful+Modulation+of+Brain+Activity+in+Disorders+of+Consciousness.&rft.issn=0028-4793&rft.date=2010&rft.volume=&rft.issue=&rft.spage=&rft.epage=&rft.artnum=&rft.au=Monti+MM&rft.au=Vanhaudenhuyse+A&rft.au=Coleman+MR&rft.au=Boly+M&rft.au=Pickard+JD&rft.au=Tshibanda+L&rft.au=Owen+AM&rft.au=Laureys+S&rfe_dat=bpr3.included=1;bpr3.tags=Philosophy%2CNeuroscience%2CJournalism%2C+Philosophy+of+Mind%2C+Philosophy+of+Science%2C+Medical+Ethics%2C+Behavioral+Neuroscience">Monti MM, Vanhaudenhuyse A, Coleman MR, Boly M, Pickard JD, Tshibanda L, Owen AM, & Laureys S (2010).

but wordpress changes it to:

<span class="Z3988" title="ctx_ver=Z39.88-2004&rft_val_fmt=info%3Aofi%2Ffmt%3Akev%3Amtx%3Ajournal&rft.jtitle=The+New+England+journal+of+medicine&rft_id=info%3Apmid%2F20130250&rfr_id=info%3Asid%2Fresearchblogging.org&rft.atitle=Willful+Modulation+of+Brain+Activity+in+Disorders+of+Consciousness.&rft.issn=0028-4793&rft.date=2010&rft.volume=&rft.issue=&rft.spage=&rft.epage=&rft.artnum=&rft.au=Monti+MM&rft.au=Vanhaudenhuyse+A&rft.au=Coleman+MR&rft.au=Boly+M&rft.au=Pickard+JD&rft.au=Tshibanda+L&rft.au=Owen+AM&rft.au=Laureys+S&rfe_dat=bpr3.included=1;bpr3.tags=Philosophy%2CNeuroscience%2CJournalism%2C+Philosophy+of+Mind%2C+Philosophy+of+Science%2C+Medical+Ethics%2C+Behavioral+Neuroscience">Monti MM, Vanhaudenhuyse A, Coleman MR, Boly M, Pickard JD, Tshibanda L, Owen AM, & Laureys S (2010).

Any help would be appreciated!!!
